Fixes issue #198 (Load searches opens save dialog)
Fixes issue #197 (Add options to search null in numeric fields)
Adds support for SSL/TLS encryption for RMI.  Accepts property encryption=disabled, encryption=no_client_auth, or encryption=with_client_auth in config file.  (The last option requires the client have a certificate in addition to the server).  Needs testing once we get a certificate.  Ref: issue #210
